Delaboratory is a color correction utility for digital images.  It
features:

* Floating point precision (not 8-bit like Gimp, not 16-bit like most
raw processors)

* Native support for multiple colorspaces (sRGB, ProPhoto RGB, LAB,
CMYK, LCH, HSL, HSV, BW)

* Non-destructive editing (adjustment layers)

* KISS design, realtime preview

* Basic operations: CMYK curves, CMYK levels, RGB curves, RGB levels,
white balance in LAB, saturation in LAB, LAB curves, BW curve, HSV
equalizer, LCH equalizer, recover shadows/highlights, vignette, local
contrast, LAB/BW/RGB/CMYK gradients

* Expert operations: levels, curves, equalizer, exposure, saturation,
white balance, fill, tone, local contrast, auto_dodge/auto_burn,
sharpen, vignette, gradient, gaussian blur, recover highlights, recover
shadows, channel mixer, high pass, c2g, copy

* Many blend modes (multiply, screen, overlay, inverted overlay, dodge,
burn, add, grain extract, grain merge, sub, difference, darken,
lighten), color/luminosity blending for RGB and CMYK

* RAW support (via dcraw), up to 5 color samplers, histograms and color
